THERMOMETER CASE.

Application filed March 17, 1928. Serial No, 95.343.

This invention relates to improvements' in lhermomcter cases, particularly off the type wherein tvvo thern'ioineters are vseparately housed in a single tubular body, in which is telescopically disposed a bushing or sheath \formed with similar pockets arranged si'de hy side, in which the thermometers are dis posed.

'llhe primary object ot this invention is to provide novel, simple and effective means for `retainingthe thermometers in their rel t0 permit the thermometers to' be readily ap` plied to and removed from the case. And a further object 1s to provide a retainer for i thermometers that is gritless and not liable to abrade, chate, or otherwise disfigure or injure the vitreous bodies of the thermometers.

rIhe various features and parts of thel invention will be understood from the de tailed description which follows, and'by reference to the accompanying drawing, in which- Figure 1 an elevational View of the complete case with the cap attached. Fig. 2 is a central longitudinal section showing' two tl'iermometerre sheathed in the unitary bushing; alsoislunvinfr the disposition of the retaining' member. Fig. 3 is an enlarged lonl 1gitudinal section, taken on line 3-3 ot Fig. 2; showing the fhern'iometers held in place bythe common retainer. Fig, 4 is a longitudinal section through one of' the sheaths, and also through the rubber member, taken substantially on line el-al of Fig'. G. Fig. 5 is respectively a top and a bottom end View of the case, as shown in Fig. 1. Fig. 6 is a cross-section taken on line 6 6 of Fig'. 3.

0 Fig. Z is a. similar section, taken on line 7-7 of Fig. 4f. Fig' 8 is respectively a side and an end elevation of a modification, comprising two oppositely facing' retaining mernbers. Fig. 9 is a cross-sectional view similar to Fig. 6; showing the application of two retainers to the vtwin sheaths. And Fig. 1l) is a view, showing' a modified retainer.

In the drawing, Q-represents the tubular body of' the caSeQhaving a closed end 2 and a normally open externally threaded end 2". 3 represents a eap Whose open end 3. is internally threaded for engaging the threads of the body 2. The body 2 is preferably of such dia-n'ieter as to readily accommodate two thermometers, as lL-4', the latter being disposed in a one-part bushing, which is formed with similar' parallel pockets or sheaf'hs .ff-Ji, Qthe said bushing' being,r preferably made of relatively thin tiexible metal, and so constructed and applied that the bushing is held in the tube 2 by its own tension. The .bushing 5 is preferably made from a tube which is operated upon by dies or other tools, for creasing' or tintin;V its opposite sides, as' at 5b, 'for l'n'ovidinnj the individual sheaths 5-5. The creases I correspondingly slotted, as at 5u, to receive a tongue-like portion 6', of a rubber or other `tenacious block or member 6, as shown in F ig's, 3, 4, 7 and 9. The men'iber G is pre ferably formed with an integral elongated head` (3a, Whose opposite sides C" are molded to conform to the oppositely curved or rolled 'walls of the adjacent sheaths, as best seen in Figs. 6, 7 and 9. The head 6 may be of any suitable size and shape and is preferably ofsuch depth as to span the spacehetween the bushing and the adjacent inner Wall of the tube 2, .as shown 1n The modified retainer shown lin F 10,

comprises -a vsingle piece or body of rubber 8having thev appearance of a dumb-bell, in which `the enlarged ends 8 aresubstantially cone-shaped and are connected by a rela.- tively thin fiat -vveb 8a,'vvhichperfor1ns the same function as the tongue G of the retainer 6. According to Fig. 10, the luted sides of the lmshinfl?T .5d-'are formed withv reg-- or tucks 5h, are,

istering circular openings 56,'Whieh are preierably smaller in diameter than the heads 8. To apply the member 8, the heads 8 are compressed sufficiently to permit them to be v inner Wall of said tubular body.

forcibly inserted throu h the openings 5". Theheads 8 are then a lowed to expand to their normal size, for rendering the member 8 self-retaining.

Obviously, the tenacious tongue-like portions 6 andl 8, which comprise the essentially novel and material features ot' the present invention, may be held in the operative positions by any suitable means, instead of the heads 6 and 8a, Without departing from the spirit of the invention.

Having thus described my invention, what I claim,'1s-

l. In a thermometer case, the combination with a tubular body adapted to house two thermometers, and a two-pocket sheath telescoping said body, of mea-ns for retaining the thermometers in said pockets, comprising a member of the consstency of sponge rubber ada ted to be inserted between said pockets an to tenaciously engage both thermometers, said member being supported by an integral enlarofement that engages the Walls of said sheath.

2. The combination with the tubular body of a thermometer case, and a two-pocket sheath for thermometers telescoping said body, said sheath having a slot'connecting with both pockets, of an'elastic tenacious member having a tongue adapted to be inresales serted in said slot and partially obstructing both of said pockets, and said member havlng an enlarged head vthat engages the outer surface of said sheath and contacts With the 3. In a thermometer case, the combination with the tubular body, and a sheath having separate pockets for housing tvvo thermometers telescoping said body, said sheath having an opening formed between said pockets, of an elastic retaining member having a tongue-like portion that is adapted to be V inserted in said opening and partially obstrueting both of said pockets and having an enlargement extending beyond the tonguelike portion adapted to prevent the accidental release of said tongue-like member.

fi. Ina thermometer case the combination with a tubular body, and a thermometer sheath having separate parallel pockets telescoping said body adapted to receive two thermometers, said sheath having a slot between said pockets, of means for retaining the thermometers in said sheath comprising a body of tenaeious material lilling` the said slot and extending into said pockets adapted to be irietionally engaged by the thermometers, said retaining body having a head that spans the space between the sheath and the inner wall of said tubular body for holding the retaining body in place.

in testimony whereof I aix my signature.

GEORGE H.- FAICHNEY.
